Torall whom it may concern.-

Be it known that I, GEORGE F. THORN, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Columns for Building Construction, of which the following is a specification. I a Y My invention relates to columns adapted to be employed as materials of construction;

and its novelty consists in the construction and adaptation of the parts, as will be more y hereinafter pointed out.

The purpose of the invention is to provide columns arranged series, each made of. a casing of light' strong metal like rolled steel and a filling of cement and provided with intermediate couplings of cast metal-for instance, cast-iron whereby column resembles the ordinary cast-iron column construction and can be used in place' of such cast-iron construction, but all of the-columns constitute, in'efiect, a monolithic or integral structure, together with certain other features and elements whereby the column is especially well adapted to be employed in certain usual forms the drawing there is represented a central vertical section of a series of columns embodying my invention. The parts bein usually cylindrical in' shape, no sectiona views need be shown in order to disclose the invention.

I wish to construction of the present invention by the statement that'it forms one of a series of columns which I have invented and for which I have filed several applications for United States patents, of which the others are as follows: Serial N 0. 277,213, filed September 6, 1905; Serial No. 283,099, -filed October 17, 1905, and Serial No. 290,427, filed December 5, 1905. All of these concurrently-pending applications contain certain generic features in common relating to a column which comprises an exterior casing having a filling of cement or other suitable material, a member which is seated upon the casing and is adapted to support the casing above and also to support the floor or other beams or girders, and a means embedded in the filling and connecting one member with a contiguous casing or casings, or two or more casings with each other. I

The novel features common to this and any other cases are not broadly claimed herethe top of each of any suitable of building.

. tegral with the body premise the description of theous filling within the whereby a most advantageous structure is provided which, among other things, permits the use of a continuous filling of cement throughout the length of the series. A seetional column is thus formed which to a high degree is, in effect, a monolithic or integral structure and which may be built of any required height and possesses all the requisites of a most efficient column of pleasing ap earance.

the drawing, 1 is a shell or cas' size, shape, and material, but preferably of a cylinder of rolled steelsuitably secured together at its edges.

2 is a cap or top therefor preferably made ofcastnmetal as cast-iron, and having a cy-' lindrical body 20, a downwardly-extending restricted neck 21, and an ing restricted neck 22, being with the body and spaced apart vertically from each other to leave a tubular body of predetermined definite or appreciable length shoulders 23 and '24' made formed at the junction of the necks between them. Externally-projecting flanges 25 25 are provided and preferably made mof this cap or'to for the purpose of affording support for t e I- beams or other elements of construction.

Above the cap 2 is placed a second shell or casing 10, the lower rim ,of which rests upon and is supported by the shoulders 24 24 of the cap. Above this second shell 10 is placed another cap 200-, in all respects like the cap 2, and above this is a third shell 100, and so on until the series is crowning-cap 120 being the uppermost member of the series. This crowning-cap has a downwardly-extending neck 211, but its tubular body 212 is flat plate or disk 213 instead ofwith the u wardlyextending restricted neck of t e other caps or tops.

The entire interior of the columns. and caps and the space between the necks of the caps and the surrounding casings, when an such space is permitted to exist, is filled wit cement 30, which serves to lute or firmly connect together the parts completed, a

provided at the top with a l and forms a continu-' series of columns, so

. vertical direction, in which direction the colthat the entire structure becomes monolithic or unitary in its nature.

Where it is deemed desirable and an additional strength and rigidity is sought to be secured, a central connecting-rod 40, of any suitable material, such as steel or a steel tube filled with cement, is inserted centrally with.- in the cement filling.

It will be observed that the caps or tops placed intermediate the cement-filled steelcasings serve as couplings for such cas-.

ings and unite them firmly together without any projecting straps, ridges, or flanges except the brackets provided forthe support of the beams, as above stated.

The caps or couplings are preferably made of substantiaily the same external diameter as that of the steel casings which they serve to unite, whereby the strains are transmitted vertically, all the weight upon the girders passing downward through the column in a 2. The combination with two hollow col-- umns arranged in vertical series, of an inter- 1ned1ate cour ling comprising a t'ubular'b'ody of substantlaily the same external diameter as the columns and provided with a down- 'wardly-extending restricted neck adapted to fit within the interior of the lower column and an upwardly-extending restricted neck adapted to fit within the interior of the upper column, the space between the necks and col- I umns and inside of the necks and columns being filled with cement, and a connectingrod embedded in the cement and extending through the coupling and into the columns.

3. The combination with twohollow columns arranged in vertical series, of an intermediate coupling comprising a tubular body of substantially the same external diameter as the columns provided with one or more laterally-extending brackets and provided with a downwardly-extending restricted neck adapted to fit within the interior of thelower column and an upwardly-extending restrict ed neck adapted to fit within the interior of the upper column, thespace between the necks and the columns and inside of the necks and columns being filled with cement.

4. The combination with a plurality of hollow columns arranged in vertical series, of

scans intermediate coupling-pieces, each inserted in the top of one column and the bottom of the next column of the series, and provided 6. The combination with a plurality of i hollow columns arranged in vertical series, of intermediate coupling-pieces, each inserted in the top of one column and the bottom of the next column of the series, and provided with an internal filling of cement extending continuously through all of the columns and couplings, each coupling-piece being of substantially the same external diameter as the columns and each provided with one or more laterally-extending brackets.

A column for building construction, comprising a hollow casing made in sections, hollow couplings connecting a plurality of the casing-sections with each other, a reinforcing element which extends through the hollow coupling from one casing-section to another and a filling of cement which surrounds the reinforcing element and extends continuously through the casing-sections and coupling.

in the filling and extending substantially throughout the length of the column.

9. A column for building construction, comprising a casing sectional and an interior filling; the casing having its sections united by a coupling-piece comprising a tubular body of approximately the same diameter as the casing-sections, having spaced shoulders which engage the contiguous ends of the sec- 9 tions, respectively, and restricted necks which extend into the sections, and the filling extending continuously through the sections and coupling-piece.
